stainless steel Johnson screen plate, also called wedge wire flat screens, wedge wire panels, are manufactured with stainless steel surface profiles and support profiles. The surface profile are welded onto support profiles at each intersection in a 90 degree.
     Wedge wire screen panels are composed of surface profile and support profile. The surface profile is commonly triangle wire, and the support profile can be triangle wire, wedge wire, round bar and rectangular bar. They can suit different machines and can be used in various applications.

Application for Wedge wire filtering tube for well drilling:

The v wire wedge wire screen pipe are mainly used for the water-treatment , water well drilling ,oil well drilling ,mineral processing, coal-cleaning plant ,sewage treatment and other industries,water, oil or gas filter and other filtration equipment

Advantage for Wedge wire filtering tube for well drilling:

1. Non-clogging construction: The V-shape section plane of wedge wire screens (Johnson type screens) creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.
2. Large Filtering Area: The consecutive slot of wedge wire screens (Johnson type screens) have wider open area,
and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better,
which can increase the water yield and prolong service time of the well.
3.Long service life Wire and support rods are all-welded, which makes wedge wire screens (Johnson types screens) more robust and longer life.
4.Excellent construction strength: The longitudinal support rods and the continuous slot make the wedge wire screens(Johnson type screens) have more excellent pressure-resistant performance.
5.Specifications and end connections of wedge wire screens(Johnson screens) can me fabricated according to customers’ requirements.
